Sometimes known as dupion or douppioni, silk dupioni is created with the threads from two different silk worms. When two worms spin their cocoons close together, the fibers get tangled up; these naturally tangled fibers are then used together to make the silk thread. The thread is rougher than regular silk, and contains bumps and irregularities where the fibers from the two cocoons are combined. Silk dupioni takes dye well and is usually easy to sew. Silk dupioni has an advantage over some other types of silks, in that it tends to resist wrinkles,which helps to enhance the usability of the finished fabric. In addition, silk
dupioni also has a tendency to take creases very well, which can give the final product a
crisp and formal appearance. As an added bonus, the fabric is totally reversible, so it is
perfectly acceptable for both sides of the material to be visible.

Silk dupioni can be used
in a number of different fabric creations. In the way of clothing, this fabric works well for
flowing jackets, blouses, skirts, dresses, and bridal gowns. For home decorating, silk
dupioni can be utilized as drapery panels or other types of window treatments, table
runners and cloths,and doilies for accent on tables and sofa backs and arms.
